Maintenance Section 412 Part Number 000007651 05/10MANITOWOC’S CLEANING TECHNOLOGYManitowoc Flake Ice Machines include technology that allows the initiation and completion of a cleaning or sanitizingcycle at the flip of a switch. This cycle will permit cleaning of all surfaces that come in contact with the waterdistribution system. Periodic maintenance must be performed that includes sanitizing the bin and adjacent surfaceareas, which are not contacted by the water distribution system.Depending on local water conditions Manitowoc recommends initiating preventative maintenance cleaningprocedures between the 6 month cleanings.This preventive maintenance removes mineral build-up from the evaporator, which results in peak efficiency andlower operating costs.This technology will also allow initiation and completion of a clean or sanitize cycle, after which the ice machineautomatically starts ice making again.Refer to the cleaning/sanitizing procedure for complete details.PREVENTATIVE MAINTENANCE CLEANING PROCEDUREUse Ice machine cleaner part number 000000084 only.This cleaner is used to remove lime scale or othermineral deposits. It is not used to remove algae or slime.Refer to “Cleaning/Sanitizing Procedure” for removal ofalgae and slime.
